Apple Unveils Its First Custom Modem Chip in the iPhone 16e
In a pivotal advancement, Apple has officially introduced its inaugural custom-built modem chip, dubbed the C1, within the newly announced iPhone 16e. This move marks a critical step towards diminishing its dependency on key suppliers such as Qualcomm. Yet, it is important to note that the C1 does not incorporate support for high-speed mmWave 5G technology—a shortcoming anticipated to carry over to the forthcoming ultra-slim iPhone 17 Air model.
The C1 modem claims to be Apple’s most energy-efficient cellular component thus far. However, users are limited to sub-6GHz 5G networks only; this exclusion means they won’t tap into the lightning-fast capabilities of mmWave service in hotspots like stadiums or busy urban centers.
Implications for Future Models: The iPhone 17 Lineup
Industry experts such as Bloomberg’s Mark Gurman and respected analyst Ming-Chi Kuo indicate that similar limitations will persist with the upcoming iPhone 17 Air model as it too will employ the same C1 modem sans mmWave support. Conversely, other models in Apple’s latest series—the iPhone 17, iPhone 17 Pro, and Pro Max—are rumored to continue relying on Qualcomm’s devices. This ensures those models will maintain complete access to both sub-6GHz and mmWave functionalities.
The Differences Between Connectivity Options: MmWave vs Sub-6GHz
Understanding the distinctions between mmWave and sub-6GHz technologies is essential. MmWave provides incredibly fast data rates but at short ranges—ideal for crowded public venues—while sub-6GHz covers wider distances albeit with modest speeds. In fact, across many regions globally, networks utilizing sub-6GHz technology significantly outnumber those deploying mmWave systems.
The Path Ahead: Next Generations of Apple’s Modems
Eagerly looking ahead, Gurman reports that Apple is already working on its second-generation modem chip designed specifically with mmWave capabilities in mind. The anticipated release aligns with Apple’s expected new product line for iPhones arriving in 2026 with download speeds projected up to an impressive rate of nearly 6 Gbps—a marked improvement over the current capability of around 4 Gbps seen in the C1 chip.
An even more advanced third-generation modem from Apple could grace consumers by late 2027 as well; expectations are high that this new iteration may surpass Qualcomm’s offerings regarding performance metrics and integrated AI features.
A Strategic Partnership with Qualcomm Through Mid-Decade
Notably, Apple’s existing partnership agreement with Qualcomm remains intact until at least mid-decade (2026), granting ample opportunity for refinement of their proprietary modem technology while still benefiting from full access to robust Snapdragon modems across their flagship smartphone lineup during this transitional phase.
